One of the most appealing aspects of this quartet for me is witnessing the development of the characters. Diane's transformation from a state of fear to one of trust and strength is truly remarkable. Additionally, her evolution from seeing the world in absolutes of good and evil to recognizing the gray areas in between is not only significant but also often overlooked. This growth adds depth and complexity to her character, making her journey all the more engaging.
However, I must admit that I would have preferred a bit more closure. After the events of the story, it would have been nice to have a small scene showing Diane meeting up with her parents at the equinox. This would have provided a sense of resolution and tied up some loose ends. It would have given the readers a better understanding of how Diane's life continued after the main events of the quartet.
